The tornado scene is considered to be incredibly realistic – even in today’s special effects standards. Arnold Gillespie, special effects director of The Wizard of Oz, created the tornado by suspending a muslin cloth from a steel gantry. Gillespie used compressed air to spray Fuller's earth, emulating the effects of a tornado. They used a model version of Dorothy's house to create the scene. Footage of the tornado was used in the 1943 film Cabin in the Sky. The tornado is the costliest scene in the movie.
